HPLC Guard Columns and Cartridges
Metrohm USA METROSEP A SUPP 4/5 GUARD
The Metrosep a Supp 4/5 Guard/4.0 reliably protects the Metrosep a Supp 4, 5 and 7 IC anion columns against contamination from the sample or the eluent. It contains the same separation material as the Metrosep a Supp 5, is also made of PEEK, and is screwed directly onto the respective separation column with nearly no dead volume ( in.On Column Guard System in.). The guard column prolongs the service life of the analytical column, with practically no influence on its chromatographic separating efficiency. The economical price and simple handling make using the a Supp 4/5 Guard/4.0 highly recommended.

Sepax Technologies Inc Sepax HPLC Column Proteomix HIC Ethyl-NP2, 4 x 10 mm
Proteomix HIC columns are specially designed for high resolution and high efficiency separations of proteins, monoclonal antibodies (mAbs), antibody drug conjugates (ADCs), oligonucleotides and peptides via a hydrophobic interaction chromatography (HIC) mechanism. Utilizing proprietary surface technologies, Proteomix HIC-NP resin is made of non-porous polystyrenedivinylbenzene (PS/DVB) beads with narrow-dispersed particle size distribution. As shown in figure below, the PS/DVB bead is modified with alkyl groups or aryl groups that provide hydrophobic interaction with analytes. Proteomix HIC-NP resin is highly rigid and mechanically stable. In comparison to silica-based HIC phase media, Proteomix HIC-NP phases have advantages for biomolecule separations with a wide pH range (2-12) and high chemical stability.

Sepax Technologies Inc Sepax HPLC Column Proteomix RP-1000, 5 µm, Guard cartridge with holder, 2 x 10 mm
Proteomix RP packings are porous polystyrene divinylbenzene (PS/DVB) polymer resins with narrow-dispersed particle size distribution. The base matrix of the resin is made of highly cross-linked PS/DVB which functions as reversed phase for chromatographic separation. The phase structure is phenyl and substituted phenyl functional groups that enable hydrophobic interaction. These highly rigid resins are provided with the particle size selection of 5, and 10 µm. In comparison to silica based reversed phase media, Proteomix RP phases have advantages for biomolecule separations with wide pH range (1-14) and high thermal stability. At various column temperatures, the Proteomix RP phases offer special selectivity, high resolution separation with online mass spec analysis capability for proteins such as mAb (monoclonal antibody), ADC (antibody drug conjugate) and related protein fragments.
